Shape coexistence and mixing in ${}^{96}\mathrm{Zr}$

I have performed a reanalysis of mixing between the first two $0^{+}$ and $2^{+}$ states in ${}^{96}\mathrm{Zr}$. My mixing amplitude for the $0^{+}$ states is about three times a recent value, although both are small. My mixing is consistent with the $E0$ strength connecting the two $0^{+}$ states, whereas the earlier mixing gives an $E0$ strength that is too small by an order of magnitude.
